After trying other products with little or no resolve, we are finally rid of birds. We purchased a QuadBlaster from you in 2002 and our site staff are very pleased to see such great results. It started working on the first day of installation and after three months of monitoring the situation we have decided to purchase two more units for other areas of our facility.–Dan from Linear Technology Corp.

All attempts to remove pigeons have failed up until now. We installed three QuadBlasters four weeks ago at Edge Cinema when the infestation of pigeons had overrun a car park, balcony and front of our building for some years. Since installing the repellers, the pigeons have thankfully left the scene. Great results as there is no more constant cleaning of the terrible mess they constantly left behind or removing the birds which used to fly into the building itself. We are so pleased with the outcome! The product does a great job.–James S. from Sydney, Australia

Installation was simple and quick. We have not had birds in our hangar since we installed the QuadBlaster units. You have a really great product and the service/tech support was outstanding.–Jerry H. from Owis Head, ME
